|

<P><B><I>divides</I></B> is a binary function object. Its <SAMP>operator()</SAMP> returns the quotient of the first argument divided by the second argument. You can pass a <B><I>divides</I></B> object to any algorithm that requires a binary function. For example, the <SAMP><A HREF="transform.html">transform()</A></SAMP> algorithm applies a binary operation to corresponding values in two collections and stores the result. The <B><I>divides</I></B> object would be used in that algorithm in the following manner:</P>
